Abstract: TEMPERATURE COMPENSATOR FOR PRESSURE REGULATOR                ABSTRACT OF THE DISCLOSURE A temperature compensator mounted on a gas pressure regulator having a spring loaded valve in which the amount of compression in the spring is changed by moving an adjusting member of the compensator in response to changes in temperature.  The temperature compensator may include a piston and cylinder assembly containing a fluid which contracts in response to a reduction in temperature and expands in response to an increase in temperature.  The piston is in engagement with the spring and is moved to change the amount of compression in the spring in response to the change in temperature.

Abstract: 07-21-(72)A                 BIOCATALYTIC REACTOR        ABSTRACT     The invention relates to a process and apparatus for conducting continuous biocatalytic reactions which comprises a first zone and a second zone separated each from the other at least in part by a semipermeable membrane. The membrane is permeable to predetermined reactant and product materials while impermeable to catalytically active microbial cell material essentially confluently packed within the second zone. The reactant material supplied to the first zone permeates the membrane and contacts catalyst in the second zone thereby forming product material.  Product material permeates the membrane and is removed from the first zone.

Abstract: ABSTRACT "Method of transmitting digital information in a transmis-sion ring".           The invention relates to a broad-band, time-division multiplex, token-passing ring local area net-work, with which both circuit-switched and packet-switched traffic, namely data, text, picture and speech traffic can be supported. The invention has for its object to provide a method of transmitting digital information in a ring having a comparatively high transmission capacity with which rapid access to the common ring transmission means can be obtained, without however high requirements being imposed on the processing speed of the stations. According to the invention this is in principle achieved by means of a method which guarantees that per time-division multiplex frame only one time slot, which is known to the station, needs to be accessed.

Abstract: ABSTRACT   A combination cementing shoe and basket, comprising a substantially tubular mandrel having a cement basket disposed thereabout, the cement basket being maintained in a collapsed mode by an annular overshot at the bot-tom of a coupling at the top of the mandrel.  A flapper valve assembly is located within the mandrel, being maintained in an open mode by the presence of a fillup tube disposed in the valve orifice.  The bottom of the fillup tube is secured to a slidable ball seat located below the flapper valve assembly.  The ball seat is initially secured in place by attachment through a plurality of shear rods to a tubular activating sleeve disposed around the mandrel and under the cement basket, the activating sleeve being maintained in its initial position by contact with the bottom of the cement basket, which is fixed to the mandrel by a shear screw.  To operate the apparatus, a tripping ball is pumped down the casing to the ball seat, whereupon the casing pressure would cause the basket shear rods, acted upon by the activating sleeve, to shear, the basket moving downward and out from under the coupling overshot.  Continued application of pressure causes the activating sleeve screw to shear, allowing the ball seat to move to the bottom of the mandrel, and removing the fillup tube from the flapper valve orifice, per-mitting the flapper to close.

Abstract: ABSTRACT OF THE DISCLOSURE         A cordless telephone in which communication between a base unit connected to a telephone network and a handset unit is carried out by radio waves, includes a transmitting and receiving system in the base unit and a transmitting and receiving system in the handset and first and second control circuits provided in the base unit system and in the handset, respectively, each include a detecting circuit for detecting whether any signal is present in an initally selected channel at the time communication is to be initiated between the base unit and the handset unit.  Such signals being present in the initially selected channel may be caused by interference from other cordless telephone systems in the vicinity.          Channel selector apparatus acts to change the base unit and handset from the occupied channel to a vacant channel.          Depending on whether it is an incoming call or an outgoing call either the first control circuit of the base unit or the second control circuit of the handset selects the vacant channel in response to an instruction command from the other control circuit.

Abstract: ABSTRACT:         :    An electrode supporting conduit tube for electrical heating of undergound hydrocarbon resources comprises a metal conduit tube and an insulating member adhered on and around the outer peripheral surface of the metal conduit tube.  The insulating member is a laminated body of a web of glass fiber impregnated with water-dispersion varnish of a hot-water resistant and thermoplastic resin and a polyether/ether/ketone resin film, which is formed by first alternately winding the glass fiber web and the resin film on and around the outer peripheral surface of the metal conduit tube for a plurality of winding turns, and then subjecting both polyether/ether/ketone resin film and glass fiber web thus wound on and around the metal conduit tube to shaping under heat and pressure at a heating temperature of from 350°C to 450°C and under a pressure of from 10 kg/cm2 to 200 kg/cm2.

Abstract: Abstract of the Disclosure:         In a circuit arrangement comprising a three port isolator (21) which has input, output, and dummy ports (33, 22, and 23), an admittance element (41 to 43) is connected at a position or positions selected between the input and the output ports, between the output and the dummy ports, and between the dummy and the input ports.  When the isolator comprises a strip line conductor having branches connected to the input, the output, and the dummy ports, the admittance element may be an extension or extensions of the branches.          The output port is connected to an amplifier (14) directly or through an inductance element (34).  The connection of the admittance element makes it unnecessary to connect a matching circuit which is otherwise essential between the isolator and the amplifier.     (Fig. 2)

Abstract: ABSTRACT            An amplification circuit for hearing aids performs independent amplification of different frequency bands of the signal generated by a microphone of the hearing aid, to match the loss of hearing of a user of the hearing aid.  Prior to this multi-band amplification however, the microphone output signal is passed through an optional filter having a characteristic which is the inverse of the spectrum of long term speech, and through a signal compressor.  The signals from the multi-band amplification are combined using an adder and the combined signal is modified by a control signal derived from the envelope of the signal generated by the microphone.  The result of this processing is to cause the range of spectral shapes present in received signals to be enlarged or exaggerated in the output signal, but to cause the range of overall levels present in the received signal to be decreased in the output signal. The processing thus increases both signal comfort and signal descriminability for the hearing impaired user of the hearing aid.
